Book: Where have all the creatures gone? Unit 1: Why Do Organisms Look the Way They Do?
Unit overview: (Narrative description of unit purpose)- In Learning Set 1, students are introduced to the Driving Question and the ecosystem mystery. Lesson 1 introduces biology as the study of living things and provides the opportunity to go outside and observe living things. Students use their observations and images of living things to raise initial questions about what could cause a population to change. This brainstorming activity is organized on the Driving Question Board. In the second lesson, students are introduced to the specific population they will be investigating: trout in the Great Lakes. They examine graphs of how this population has changed over time and read about the effect that decreasing trout has had on fisherman in the region. Learning Goals: Students will understand: 1. Biology is the study of organisms interactions between organisms and the environment. 2. Organisms have specific survival needs. 3. In order to understand a general question scientists sometimes look at a specific case.

Unit 2: What is Food for Living Things? Unit Overview: In the second learning set, students focus on the food quadrant of the Driving Question Board: If starvation caused the trout population to decrease, do we know why? Why is food so important? In this learning set, students discover that food provides living things with building materials and the energy necessary to grow and do things. Students learn that food must contain one or more of the following: fat, protein, and/or carbohydrates. Students test various foods to determine if they contain these substances. This learning set explores photosynthesis, as students realize that everything they eat is connected to plants and that plants do not eat, so they must make their own food. Photosynthesis will be covered in a different IQWST unit, so this learning set does not go into detail about the process itself. The second learning set introduces scientific principles, which are statements of general science knowledge. Principles about food and why it is important, agreed upon by the students, are recorded on a class list. Students use these principles to defend their claims in evidence-based explanations. With the teacher modeling and scaffolding the process, students construct one explanation and evaluate another. Students construct an explanation that defends the claim that water is not food. Constructing this explanation helps confront a common student conception that living things get energy from water. Students then help the teacher choose the most convincing explanation to defend the
claim that plants need food. Choosing between explanations allows students to evaluate why some explanations are more convincing than others, thereby helping solidify the components of an evidence-based explanation. Learning Goals: Students will 1. identify various substances found in food. 2. describe the function food serves in organisms. 3. construct and defend an evidence based explanation about whether a specific substance counts as food. 4. Students will identify the presence of a food substance in plant parts. Activities: 1. Students analyze food labels to find evidence of what substances are found in various food. 2. Students test common foods and examine water for the presence of carbohydrates (starch and sugar), proteins, and fats. 3.

Develop and use models to describe unobservable mechanisms. 2. Develop a model to describe phenomena 3. Construct a scientific explanation based on valid and reliable evidence obtained from source.

Unit Overview: In Learning Set 3, students return to the trout mystery and Driving Question Board using information about food to help determine what happened to the trout. This learning set begins with an introduction to food webs as students consider the possibility that maybe the trout is not getting enough food or has a predator. Students construct a preliminary
definition of the word ecosystem in this lesson that will be refined in Lesson 11. Students are introduced to the sea lamprey, an invasive species that eats trout. Students examine graphs of the sea lamprey population and consider the possibility that the sea lamprey is causing the trout population problems. This learning set concludes with students investigating what could make the sea lamprey a successful predator. While dissecting the sea lamprey, students learn that the structure of the sea lamprey makes it very good at attacking trout. This introduces students to the scientific principle that organisms have different structures that help them perform functions such as eating and reproducing. Learning Goals: Students will 1. identify the type of relationships, such as predator/prey and producer/ consumer, that exist between the organisms in a food chain or food web. 2. analyze a change in a population in a food web to determine its direct and indirect effects. 3. analyze a food web to determine how changes in a population affect the entire food web. 4. analyze and describe the effects of an invasive species in an ecosystem. 5. analyze a variety of structures and related functions such as eating, moving, reproducing, and breathing. 6. analyze observational data to determine how an animal s structure contributes to its ability to obtain food and reproduce. 7. construct and defend evidence-based explanations about how an organism s structures help it perform the functions necessary to survive. 8. analyze observational data to determine how an animal s structure contributes to its ability to get food and reproduce.

Unit 4: How do organisms compete? Unit Overview: In Learning Set 4, students investigate the ways organisms affect one another. In Lesson 9, they work with a computer model of an ecosystem containing foxes, rabbits, and grass. They examine how the percentage of grass in this ecosystem affects the rabbit and fox populations, and then they construct a scientific principle about competition for resources. Students then examine the effects of an unknown invader on their computer ecosystem, observing population fluctuations to determine what the invading organism eats. This lesson concludes with students using the evidence-based explanation framework to guide a debate in which the class attempts to reach consensus regarding the invader s food source. This debate serves to help motivate the practice of evidence-based explanations. Trying to
convince one another of a claim helps students experience the importance of each of the elements of the explanation framework. For example, they realize that an explanation without evidence is not convincing. In Lesson 10, students use their new understandings about how organisms can affect one another and how to read population graphs in order to analyze the trout mystery further. After examining their graphs, they realize that the trout s food source is increasing, not decreasing, so the trout must not be starving. Students then realize that while the sea lamprey appears to affect the trout, it is not the whole story. The trout population started to decrease before the sea lamprey entered the Great Lakes. Learning Goals: Students will 1. identify the resources for which organisms within a population are competing. 2. identify the type of relationships, such as predator/prey or producer/ consumer relationships in an environment. 3. analyze data gathered from a model to find patterns that identify the resources and competitors of an invasive species (a new competitor). 4. analyze data gathered from a model to use patterns to determine a predator/prey relationship. 5. analyze graphs to determine the effects of adding a new predator to the ecosystem. 6. construct and defend an evidence based explanation about the predator/prey 7. predict how populations will change when there is a change in their food web.
8. analyze graphs to identify the effect of adding a new predator to the ecosystem. 9. predict how the introduction of a new competitor will affect the population of native species. Activities: 1. Students explore the NetLogo model to identify organisms in an ecosystem and how they interact. 2.

Analyze and interpret data to provide evidence for phenomena. 2. Construct an explanation that includes qualitative or quantitative relationships between variables that predict phenomena. 3. Construct an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem. 4.

Unit Overview: Learning Set 5 introduces abiotic factors and how they can affect organisms in ecosystems. This helps students finalize the definition of ecosystem as containing both biotic and abiotic factors. Students focus on dioxin, an abiotic factor affecting trout. Students examine graphs of dioxin and realize that it has been at unacceptable levels since the trout population started to decline. This is recorded on the Driving Question Board and is the final piece of the puzzle for students. Students review the data along with scientific principles to construct scientific explanations about what affected the trout population. Given the data they collected, there are three plausible and acceptable claims: (1) the sea lamprey affected the trout, (2) the dioxin made the trout population decrease, and (3) both the sea lamprey and dioxin affected the trout. The third claim is the most accurate, but each of these claims is acceptable and defensible, given what students learned. Finally, students debate their different interpretations of the data and recognize the
complexity that exists in ecosystems: each of the factors affects each of the populations. Students are provided the opportunity to apply what they have learned about how different factors affecting an ecosystem can impact populations. Learning Goals: Students will 1. Students will analyze data to determine the effects of an abiotic factor on an organism. 2. Students will analyze data to determine the relationship between biotic and abiotic factors in an ecosystem. 3. analyze data to identify relationships between abiotic and biotic factors in an ecosystem. 4. use relationships between organisms to construct and defend evidence based explanations about how the addition of an invasive species affects the native species. 5. construct and defend evidence based explanations about how abiotic and biotic factors in an ecosystem affect population sizes Activities: 1. Brainstorm a list of biotic and abiotic factors in ecosystems then investigate the effect of moisture on earthworms in order to see how an abiotic factor can affect living things. 2. Analyze dioxin data and compare it to the data and compare it to the data they have previously examined on the trout, chub, and lamprey. 3. Construct scientific explanations to answer the questions, What is causing the trout population to change? Science & Engineering Practices Students will be able to:
1. Construct an explanation that includes qualitative or quantitative relationships between variables that predict phenomena. 2. Construct an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem. 3.

Book 2: What is going on inside me? Unit 1: What is going on inside me? Unit Overview: Pictures and discussion of everyday physical activities and the body s responses, such as breathing hard or sweating, are used to spark questions about what could be happening inside our body to enable us to do these things. The goal of looking inside the body leads to the observation that our bodies contain cells, seen in samples taken from students cheeks and skin and slides of heart cells. A Driving Question Board (DQB) is used to organize questions about what is inside the body and what cells have to do with helping the body do what it does. This motivates an exploration of cells in the environment around us in Lesson 2. Students observe living cells in samples of yogurt and pond water, determine that these cells are living things, and compare them to the cells found within multicellular organisms. The recognition that there are different levels of organization in living things motivates Lesson 3, an introduction to studying systems. Students dissect a simple system a pen to develop the idea of analyzing the structure and function of a system, its subsystems, and its parts. Students begin to apply the idea of systems, subsystems, and parts to the human body. The idea of disruptions to subsystems causing overall problems is introduced and becomes additional motivation to figure out how the subsystems work together to accomplish the body s needs.
Learning Goals: Students will 1. describe cells from a multicellular organism. 2. think more deeply about the role of cells in the body. 3. ask empirical questions based on observations and compare characteristics of cells in single-celled organisms and multicellular organisms. 4. ask questions whose answers will help them explain why single-celled organisms are living things. 5. identify cells and their cell parts that are visible through a microscope. 6. analyze a system to determine its components and functions and how they interact. 7. use evidence to explain why the body is a system.

Unit Overview: The second learning set focuses the Driving Question on tracking food and energy through the body to figure out how the body gets the energy it needs from food. Students start with the digestive system in Lesson 4. They observe that there is evidence of a chemical reaction occurring at the first stage of digestion, in the mouth, as well as the mechanical processes of digestion. Following food down the esophagus and stomach, students observe how stomach acids break down fat and protein in a test-tube model. They examine the structures of the small intestine and see how
the food molecules are absorbed. In Lesson 5, students investigate the role of the circulatory system in moving food molecules around the body. Data of glucose levels in the blood are used to make the connection between taking in food and an increase of food molecules in the blood. Students then investigate how the blood plasma might be able to get food to the cells in the body. Students observe how water can enter and leave cells in experiments involving onion cells. They then use a physical model to investigate how sugar molecules might enter cells through a semipermeable membrane. Next, they test whether sugar can be used by single-celled organisms as a way of exploring whether this is what could be happening in the body s cells. Students investigate what happens with yeast in the presence of either plain water or a sugar solution and notice that the yeast increase in number in the presence of sugar and that they have released a gas as waste, indicating a use of the building materials and energy in the sugar. In Lesson 6, students investigate why oxygen intake also increases with increased activity. With a simple experiment involving a candle and a jar, students demonstrate that there is less oxygen in the air we breathe out than in room air. They trace the oxygen through the respiratory system to find out where it goes and see the oxygen being carried through the blood along with the food molecules. Students consider the role of oxygen in combustion and construct an explanation of the role of oxygen in the breakdown of sugar molecules in order to supply energy to the cells. In Lesson 7, students investigate how food provides building materials along with energy. They see images of cell division and discuss where the mass needed for cell growth and division could be coming from. A reading about bone growth and healing of broken bones provides an example of how cell division explains growth and repair in the body.

Unit Overview: In this learning set, students investigate how the interactions of the various body systems are coordinated. In Lesson 8, they investigate how increased exercise triggers increased activity of the circulatory and respiratory systems. Students consider how increased energy needs lead to an increased need for food and oxygen and the increased rate of chemical reactions to release the energy results in some heat loss, thus leading to increased body temperature. Lesson 9 brings together the understandings about processing food (from throughout the unit) to construct a scientific explanation of where and how food gets used in the body, tracing from food input to use of food for building materials and energy by the cells of the body. In Lesson 10, students examine how the nervous system coordinates the activity of the body s systems. Finally, in Lesson 11, students draw on their understandings from prior lessons to address the Driving Question and explain the consequences of various disruptions to the body systems. Learning Goals: Students will
1. analyze data collected in experiments to determine how rates of respiration and circulation change to respond to the body s needs. 2. identify homeostasis as a characteristic of living things. 3. evaluate data to determine where food is used in the body. 4. construct a scientific explanation of where and how food is used in the body. 5. identify the basic structure and function of the nervous system. 6. analyze data to determine density of touch receptors. 7. construct a scientific explanation to answer the Driving Question and to address four areas: energy, system, results, and control. Activities: 1. Students record changes in heart and respiration rates during exercise and at rest. 2. Develop a scientific explanation that claims that cells are the units that use food in the body. Science & Engineering Practices Students will be able to: 1. Develop and use a model to describe phenomena. 2. Use an oral and written argument supported by empirical evidence and scientific reasoning to support or refute an explanation or a model for a phenomenon or a solution to a problem.

Book 3: Why Do Organisms Look the Way They Do? Overview: Unit 1: Learning Set 1: Why Do I Look the Way I Do? Lessons 1-4 The first learning set, composed of four lessons, focuses on the similarities and differences in traits. In Lesson 1, students first identify similarities and differences between organisms. These traits are then classified as inherited, acquired, or both. In the last activity, students are introduced to the idea that bodies carry instructions for specific traits, and DNA is identified as the molecule that carries these instructions. In Lesson 2, students investigate the distinction between inherited and acquired traits. They also start the first of two experiments using Wisconsin Fast Plants in order to collect data about how traits are inherited in plants. In Lesson 3, students examine human pedigrees in order to determine patterns in how traits are inherited. They also collect the data from the plants and set up seeds in order to observe another generation of plants. Students use multiple generations of data for both humans and plants in Lesson 4 in order to support the patterns they have identified with data they have collected. Learning Goals: Students will understand: how to identify the traits of an organism. how to identify the distinction between inherited and acquired traits. how to analyze data about the traits of an organism. how to analyze data about inherited traits to determine if two traits are related how to provide evidence to distinguish between the influence of inheritance and environment on traits. how to use evidence to support claims about patterns in heredity data how to analyze data to compare patterns between plant and animal data how to develop claim, evidence, and reasoning for heredity data Activities in this Unit:
1. Students will collect and analyze class data on selected human traits in order to determine if there are any patterns. 2. Students will taste brussel sprouts and PTC paper to determine if there is a connection between an inherited trait and the preference for certain foods. 3. Students will dissect flowers to investigate reproduction and inheritance in plants. 4. Students will analyze given pedigrees to determine patterns in inherited traits. 5. Students will grow Wisconsin Fast Plants with different colors of stems (green and purple) to determine if there is a pattern in inheritance. Science and Engineering Practices: Students will be able to: 1. Construct explanations and designing solutions. The explanation will include qualitative or quantitative relationships between variables that predict phenomena. 2. Engaging in argument from evidence 3. Analyzing and interpret data.

Overview: Learning Set 2: How Does the Inside Affect the Outside? Lessons 5-7- The observations students made and the data they collected in the first Learning Set raised the question of how the DNA that carries instructions for traits can be passed from one generation to another. In Lesson 5, students compare cell division in somatic cells in order to understand the differences and how those differences serve specific functions. In the second activity, they investigate how instructions from the same set of parents can lead to different combinations of instructions in the offspring. In Lesson 6, students construct a model of inheritance in order to explain how genetic information gets passed from parents to offspring. Students use their model to explain the data they have collected on humans in Lesson 7. Learning Goals: Students will describe how heredity instructions are organized in chromosome pairs, one from each parent. explain, using allele pairs, how an organism could carry instructions for a trait that the organism does not exhibit construct a model to explain how genetic information gets passed from parents to offspring explain how some genes are dominant over others. explain a model of inheritance for human data Activities in this Unit 1. Students will model possible gamete combinations of a fictional organism called an yllis. 2. Students will develop a model of inheritance that explains all of their observations and data about plants. 3. Students will test the model against the available evidence.

Cross Cutting Concepts Patterns Cause & Effect Scale, Proportion & Quantity Systems & System Models Energy & Matter Structure & Function Stability & Change Time Frame for Unit- Approximately 6-8 class periods Learning Set 3: Why Does Variation Matter? This learning set shifts the focus from individuals, and how genetic information gets passed on, to species and populations and variation within them. In Lesson 8, students investigate traits with multiple variations and analyze data about the distribution of those variations from three different populations. They also engage in an activity about how to best represent those data. The lesson concludes with a teacher-led exercise in order to develop the concept of a gene pool. Lesson 9
